IMPROVEMENT IN BELT-TWIS'TING APPARATUS.

Specification forming part of Letters Patent No. 164,702, dated J une 2 2, 1875 applica-tion led May 1o, 1875. i

To all z chom t may concern:

Beit known that I, MosEs P. WILMARTE, of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain Improvements in Belt-Twisting Apparatus, of which thevi'ollowing is a specication:

My said invention relates to a simple and effective means for twisting belts or for mak ing round belting, and consists oi a reel hung in a revolving rack, the latter having a tubular projection, in which there is inserted a spindle, so constructed as to form a tension to govern the outward-moving belt, and over which said belting material passes to a receiving-drum, around which the completed belt is wound.

rlhe accompanying drawing is hereby made a part ot' this specification, similar letters of reference indicating corresponding parts.

Figure l of said drawing is a side view of said device, and Fig. 2 a top view thereof'.

a a are the base and uprights, which support the operating parts. cis the revolving rack, and l is the handle or crank by which the same i`s turned. e is the interior reel on which the belfing material is coiled; and j' is a crank onhandle by which said reel is operated, as hereinafter mentioned. gis the tubular projection above mentioned. h shows the said spindle; and i a revolving drum, which receives the completed belt, lc representing the shaft of said drum, and lm the tight and loose pulleys connected therewith. n shows the completed belt wound onto the circumference of said receivingdrum v3.

The operation of said device is substantially as follows: The beltin g material is to be first coiled on the reel, to facilitate which is the office of the handle or crank f. One end ot' the beltin g material is then passed through the hollow projection g and under the inserted end of the spindle A turn of said belting material is then made around the projecting end of said spindle, and subsequently fastened into the circumference ot' the receivingdrum i. N0w, while said drum is being revolved by means of power received through the pulleys ai'oresaiththe rack c and its contents are turned by means ot' the crank or handle d, and in a direction at right angles with the line ot' the revolution or' said drum z'. The eiiect ot' these combined and simultaneous movementsis to give the belt an'even and solid twist, and to make the sameA completely round in form and appearance.

The tension of the outwardfmoving beltin g is governed by the pressure upon it of the inserted end ot' the spindle h, and this may be regulated at the will of the operator.

I claim as my invention, and desire to secure by Letters Patent- In belttwisting apparatus or machines for twisting belts, the combination of the revolv-
